Specification of Letters Patent.

Patented May 1, 1906.

Application filed September 11. 1905. Serial No. 277.939.

To all 107mm it may concern.-

Be it known that I, OLER P. VROOM, a citi- Zen of the United States,residing at Iiinncus, in the county of Iiinn and State of Missouri, haveinvented a new and useful Hay-Stacker, of which the following is aspecification.

This invention relates to that class of haystackers in which there arecombined a baseframe forming a support, a stacker-frame pivotallyconnected with said base-frame, an operating-lever with the free end ofwhich the hoisting-tackle is connected, and a vibratory frame which isoperated by the lever and which is operatively connected with thestacker-frame.

The object of the present invention is to simplify and improve thegeneral construction and operation of the device and to gain anincreased leverage at the starting-point where the loaded stacker-framebegins to rise from the ground and where the greatest amount of power isrequired.

\Vith these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and par ticularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that the right is reserved to any changes, alterations, andmodifications to which recourse may be had within the scope of theinvention and without departing from the spirit or sacrificing theefficiency of the same.

In said drawings, Figure 1 is a perspective view of a hay-stackerconstructed in accordance with the principles of the invention. Fig. 2is a sectional elevation of the same, showing the stacker-flame in fulllines in discharging position and in dotted lines in an intermediateposition. Fig. 3 is a detail view of the spring for restoring thestackermembers 1 1 and cross members 2 2, whereby said side members arespaced and connected, as well as obliquely-disposed braces 3 3, wherebythe structure is reinforced. The side members 1 1 may, when desired,constitute skids or runners upon which the device may be convenientlymoved from one place to another.

The side members 4 4 of the stacker-frame S are pivotally connected withthe outer side of the side members 1 1 of the base-frame near the rearend of the latter, the pivotal pins 5 5 being in axial alincment, sothat the stacker-frame may swing hingcdly thereon. The stacker-frame isprovided with the usual stacker-head H, which when the frame is loweredrests upon the ground in longitudinal alinement with the base-frame F,as will be clearly seen in Fig. 1 of the drawings.

One of the cross-bars 2 near the front end of the base-frame is providedwith lugs 6, between which the operating-lever L is ful' crumed upon apin 7. This lever, which normally extends upwardly from the base, ismade of considerable length, and its free end is connected with the rearcross-piece 2 of the base-frame by means of tackle, includingguidepulleys 8, 9, and 10 and a flexible element 11, such as a rope orcable, the free end of which is extended to the point of attachment ofthe draft.

Pivotally connected with the side members of the base-frame are the sidemembers of an inverted-V-shaped vibratory frame or hoisting-frame 12,provided near its apex with a pair of pivoted straps 13, extendingadjacent to the sides of the lever L and connected by means of a pin 14,upon which is ournaled a grooved pulley 15, riding upon the lever, whichaffords a track for said pulley. The apex of the frame 12 is alsoconnected with a cross-bar 16 of the stacker-head by collapsibleconnecting means 17, composed of straps 1S and rods 19, slidablyconnected with each other, so as to be capable of collapsing when thedistance between the apex of the frame 12 and the stacker-head isdiminished, thus avoiding the difficulties frequantly encountered whereflexible connecting means are used, it being of course understood thatthe straps 1S and the rods 19 are practically non-flexible.

A spring device is provided to assist in re- I tial position.

storing the stacker-head from an elevated to a lowered position, saidspring device including a rod 20, which for the sake of lightness may betubular, such as an ordinary one-inch gas-pipe of suitable length, theends of said rod or pipe being secured in socketed brackets 21 22, madefast to the lever L. Fitted adjustably upon the rod 20 is a collar 23,which may be retained in position by any suitable means, such as acotter-pin 24, engaging one of a plurality of perforations in the rod.Coiled upon the latter above the collar 23 is a spring 26, whichexercises its tension upwardly against a slide 27, fitted upon the upperend of the rod. The slide 27 has perforated lugs or ears 28 for theattachment of flexible elements, such as ropes 29, which are guided oversuitably-disposed guide elements, such as pulleys 3O 30, to thestacker-head H, with which the free ends of the ropes are connected, asby staples 81. It is obvious that when the stacker-head is elevatedbeyond a certain limit the spring will be compressed, so that when thedraft exercised upon the stacker-frame is discontinued the expansiveforce of the spring will be utilized to restore the stacker-frame in thedirection of its ini- From the foregoing description, taken inconnectionwith the drawings hereto annexed, the operation and advantagesof this invention will be readily understood by those skilled in the artto which it appertains. When the device is in its initial position, asshown in Fig. 1, the stackerhead rests upon the ground and the pulley15, carried by the straps 13, is spaced quite a distance from the freeend of the lever L, with which the tackle is connected. When a load hasbeen placed upon the stacker-head and draft is applied to the tackle, I

the lever 7 will swing in the direction of the arrow A in Fig. 1,carrying with it the vibra tory frame and the stacker-frame, the head ofwhich is thus gradually elevated. As the movement continues the pulley15 will gradually travel outwardly upon the lever L, thus graduallydecreasing the leverage in proportion as the load is being raised, thegreatest leverage being exerted at the starting-point, where it is mostneeded. Excessive strain upon the draft-animals will thus be avoided atthe starting point. When the stackerframe reaches its dischargingposition, it swings slightly beyond the vertical plane, passing throughthe pivotal points of its side members; but at the same time the spring26 will be compressed, the tension of the spring having previously beenadjusted by properly adjusting the position of the collar 23, so thatwhen the load is discharged the tension of the siaisr spring will beutilized to restore the device in the direction of its initial position.

Having thus described the invention, what is claimed is 1. In ahay-stacker, an operating-lever, a pivoted hoisting-frame, and meansconnecting the apex of the hoisting-frame with the lever and movableupon the latter.

2. In a hay-stacker, an operating-lever, a pivoted hoisting frame,straps connected with the apex of the latter, and a pulley supported bysaid straps and movably engaging the lever.

4. In a hay-stacker, a pivoted stackerframe, a pivoted hoisting-frame,and collapsible connecting means between said frames includingslidably-connected rigid members.

5. In a hay-stacker, the combination with suitablyconnected hoisting andstacker frames, of an operatingleve-r, and means connecting thehoisting-frame with the lever and movable upon the latter between itsfulcrum and its free end to which power is applied.

6. In a hay stacker, a base frame, a stacker-frame connected therewith,a pivoted hoistingframe, an operating-lever, a guiderod connected withand s aced from said lever, a spring-actuated s ide movable upon saidguide-rod, and suitably-guided flexible members connected with saidslide and with the head of the stacker-frame.

7. In a hay stacker, a base frame, a stacker frame connected therewith,a pivoted hoisting-frame, collapsible connecting means between thehoisting-frame and the stacker frame, an operating-lever, a guide-rodconnected with and spaced from said lever, a collar adjustable upon theguide-rod, a slide movable upon the latter and havinglaterallyextendingperforated ears, suitably-guided flexible elements connecting the slidewith the'head of the stacker-frame, and a spring coiled upon theguide-rod between the collar and the slide.

In testimony that I claimthe foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
